This curriculum guide was developed for use with public television's Nature series. The materials in the guide are designed to help students actively participate in the study and experience of nature. Students are encouraged to view the programs as naturalists would, observing animals in their habitats, noting their behavior, examining the environmental, economic, and political factors that affect their condition, and drawing conclusions. Each lesson in the Teacher's Resource Guide includes: (1) a "Program Overview" that presents background information and brief synopses of the program to be viewed; (2) "Before Viewing the Program" that familiarizes students with the program's subject and allows them to set purposes for viewing; and (3) "After Viewing the Program" that provides discussion questions to help students assess the main points of the program. Some lessons also contain: (i) "Objectives" that provide the teacher with measurement goals; (ii) "Vocabulary" that features definitions of unfamiliar words used in each program; and (iii) a "Naturalist's Guide" (student worksheet) to be duplicated and distributed to students. The programs highlighted in this guide examine the natural history of North America. Program titles include "The Great Encounter,""Conquering the Swamps,""Across the Sea of Grass,""The First and Last Frontier,""Confronting the Wilderness,""Into the Shining Mountains,""Living on the Edge," and "Searching for Paradise."
